Solar Street Lamps Installation and construction

Solar street lamps are powered by crystalline silicon solar cells, they have maintenance-free valve-regulated sealed batteries(colloidal batteries or lithium batteries) to store electrical energy. These Ultra-bright LED lamps are used as a light source which is controlled by the intelligent charge and discharge controllers thus replacing the traditional public electric lighting street lamps.

Solar street light powered by the sun which doesn’t require the need for cables and comes with zero electricity charges.  It has the advantages of having good stability, long life, high luminous efficiency, ease of installation, and maintenance. Solar light has both economical and practical benefits, it follows high safety standards,  operates on higher energy conservation and is environmentally friendly, solar street lamp can widely be used in urban primary and secondary roads, communities, factories, tourist attractions, parking lots, and other places.

Solar street lamp Installation Guidance and Steps:

  1. Dig a foundation pit at a depth of 1.5m from ground zero that has a square opening with a border of 0.8×8M. Put the four-corner foundation cage into the pit, and keep the extended part about 0.1 M above the ground (note that the threaded part should not be damaged). At the same time, insert a pipe with a diameter of 80MM into the foundation pit followed by concrete to get it filled.solar street lamp installation instruction
  2. Dig a battery tank foundation at a depth of 0.8-1.0 meters that has an opening of 1.0×0.6 meters around the attachment.
  3. 4-7 days after the concrete solidifies, prepare to erect the lamp pole
  4. Install the LED lamp on the lamp arm and fix it with the main lamp post.
  5. Start threading: Thread the 2.5mm2 wire (one red and one black) from the inner arm and the pole of the LED lamp to the bottom of the lamp pole and then connect it with the output end of the controller.
  6. Fix the lamp and then fix the arm.
  7. Fix the cross arm of solar panel bracket with bolts on the main lamp pole.
  8. Place the solar panel on the bracket frame and then fix the solar panel on the bracket with screws. At the same time, connect the wires from the junction box of the panel and pass them through the battery panel bracket and the cross arm to the lower part of the lamp post.                                                                                                             solar street lamp installation
  9. Fasten the solar panel bracket to each end of the cross-arm.                                                                                                  solar street light installation
  10. Put the battery into the battery box, pass the wires through the steel wire hose, and fix the bolts and steel wire hose. Place the battery into the battery tank and move the steel wire hose through the pipe of diameter 60-80mm inside the foundation. It is better to keep the steel wire hose above the ground and backfill with soil to level it.
  11. Controller wiring: Connect to the controller in the order of battery, solar panel and load (note: first “-” then “+” to prevent short circuit);solar street lamp controller
  12. The wires on the battery are connected to the fan controller and the solar controller respectively.
  13. Remove the input line of the solar panel from the solar controller. After about 1 minute, if the bulb turns on normally, it means that the line is connected correctly. Otherwise, the connection is wrong and needs to be checked. Then put the controller into the lamp pole; Erect the lamp post.
  14. Use the crane to pull up the lamp pole, align the flange hole of the lamp pole with the embedded part (pay attention to the direction of the lamp), and then fix it with screws.solar light installation
  15. Check whether or not the bolts of the lamp post and embedded part are fixed, whether or not the lamp is neat and aligned with the road, and also check whether or not the lamp posts of the complete road is neat, that is to check if all the lamp posts are in a straight line when seen from the first lamp post
  16. The installation of solar street lamps is basically the same as the installation process of traditional street lamps, but there are some differences, especially the installation of solar panels and batteries. Installation and construction procedure of solar street lamp includes a selection of lamp position, basic prefabrication, installation preparation (battery assembly, panel, and support), lamp pole assembly (thread running, lamp installation, panel technical support installation), hoisting, battery installation, controller installation, lamp pole calibration, acceptance, and handover.

Why does solar street lamps design with internal hexagonal screws?

You may find that almost all solar street lamps are designed with inner hexagonal screws. Why are solar street lamp engineers so keen on using inner hexagonal screws for solar street lamps?

You will find that 99% of the assembled furniture bought online is hexagonal. The screw head of the inner hexagon screw is round outside and concave in the middle. Such a structure has obvious advantages.


  1. Load bearing is greater.

It has six surfaces to bear the stress from a screwdriver, which is more capable of holding the screw than the one-sided screw and the cross-shaped screw with only two faces.

Note: The material of inner hexagonal bolt is generally made of stainless steel, carbon steel, and alloy steel, which are basically the same as other types of screws. The higher the performance grade, the greater the strength will do. When selecting the screw, the screw of suitable performance grade must be selected strictly according to the user requirements. The grade is different, and the price is also different.

    2. It can be buried when treatment.

That is to say, the whole nut sinks into the inner part of the workpiece, which can keep the surface of the workpiece flat and beautiful.

    3. Easy to installation.

Compared with the outer hexagon screw, the inner hexagon is suitable for more assembling occasions, especially narrow ones. Therefore, it is very convenient for assembling, repairing and maintenance.

   4. Not easy to disassemble

Our common tools are movable wrenches, screwdrivers, and solid wrenches, while the removal of hexagonal bolts must use a special wrench, so it is not easy to disassemble, which is also an advantage.

Of course, if you may think you can design many kinds of weird structures, but the problem is that the special wrench is much more complicated to be manufactured.


As for this wrench issue, some people feedback that since the inner hexagonal bolt has the advantage of strength and is designed as a sinking hole, it is difficult to screw out in case of slippage, while the outer hexagonal bolt need common tools only to do so, why not design it as the following shape?

As you know, the outer hexagonal screw head is exposed. The wrench needs a certain space to screw out it. The sinking hole should be designed large or protruding, while the inner hexagonal only needs a small sinking hole.

Hence, actual application conditions and environment determines what type of screw must be used.
